Rate conditions
Claude API standard rates; Base rate. Write rate replaces ordinary input billing for those tokens. Output and uncached input are separate. Batch, residency and service modifiers are not included.
Set top-level cache_control for automatic caching or place it on content blocks. Up to four breakpoints; longer-lived blocks must precede shorter-lived blocks.Source for How to enable it (opens in a new tab)
5m writes: 1.25× base input. 1h writes: 2×. Reads: 0.025× for Fable/Mythos 5.1, 0.05× for Opus/Sonnet 5.5, otherwise 0.1×. Host prices, long-context tiers and residency modifiers still apply.Source for Billing rules (opens in a new tab)
Limits & data boundaries
Prefix order is tools → system → messages. Cache must exist before concurrent requests can reuse it. Cache isolation is per organization, and also per workspace on Claude API, Claude Platform on AWS and Foundry.Source for Limits & data boundaries (opens in a new tab)

Observed 12 Oct 2026. Write rates and storage fees are different charges; use the billing rules above.
Use the model’s Converse cachePoint or InvokeModel cache_control fields. Legacy InvokeModel does not accept top-level automatic cache_control; use explicit blocks.Source for How to enable it (opens in a new tab)

What the measurements say
No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.
Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.
